    "We recently hired Puget Sound BnR for a full basement remodeling project, and I couldn’t be happier with the results. From the very beginning, their team was professional, knowledgeable, and easy to work with. They took the time to understand exactly what we wanted for the space and helped us turn our ideas into a clear and realistic plan. They also gave great suggestions that improved the final design without trying to push unnecessary upgrades. The entire process was smooth and well-managed. The crew showed up on time, stayed on schedule, and kept everything clean and organized throughout the project. Communication was excellent—they kept us updated every step of the way and were always available to answer questions. The quality of the work really stands out. The finishes look amazing, everything feels solid and well-built, and you can tell they paid attention to the small details. They transformed our basement into a beautiful, functional living space that we now use every day."

    "We had an outstanding experience with Sean and Bzr team. From the initial call with Gaby to the finished product. I highly and strongly recommend BZR. We first started with a bathroom addition and ended up with an ADU project which turned out great adding a kitchen and 3/4 bath. It did take time and many changes, I want to thank Sean for his patience. I would absolutely in a blink work with them again. I will upload photos when wife has finished furnishing."

We are so thankful to work with him. And he is fun!"

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.

You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website. 

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
